find 40% of 60 using two different strageties, one of which must include a pictorial model or digram?pls help

1 answer:

6 0

One way would be to convert 40% into a fraction and multiply.

40% = 2/5

2/5 * 60 = 24

Drawing a diagram could involve drawing a whole (etc. a circle) and dividing it into fifths, then shading 2 of it with each section representing 12. Hope this helps!<span />
